Abstract
A method for the simultaneous determination of sulfide and cyanide has been developed by using Ion chromatography with electrochemical detection. Most existing methods are subject to considerable Interference. However, separation of cyanide and sulfide Is conveniently untertaken using Ion chromatography. Electrochemical detection, rather than conductometric detection, commonly used In Ion chromatography, enables basic media to be used at all stages of the experiment, thereby eliminating problems associated with the formation of volatile and highly toxic hydrogen cyanide or hydrogen sulfide. A detailed study employing a wide range of electrode and electrochemical cells has been Investigated for detection of sulfide and cyanide. Dropping mercury electrodes or mercury-plated solid electrodes provide the optimum response, but the electrochemical cell design and nature of liquid chromatographic apparatus are also Important.
